The Schedule referred to inthese Letters Patent and making part of the same We,'PnIL1P CHARLES Evans, of Brimscombe, -iu

the county of Gloucester, England, and HENRY JAMES HOGG KTNG, of Glasgow; in the county of Lanark,Scotland, have jointly invented certain Improved Apparatus for gFeeding Wool, Cotton, or other ;Fibrous Materials to Oarding or other Mayendless apron, such as .is' usually employed for feed ing or;entering such materials-to carding-machines;

thematerials being weighed in separate quantities and snpplied'at regular intervals, by which means 1greater'nniformityand regularity can be obtained than ispossible with the ordinary-proeessof feeding by hand. a l

Description of the Acconwaaing Drawing. Figure-l is. an elevation of the front which fitnesthe carding or other machine. 4

, Figu'reZ is'a side elevation. r Figure 3 is an inside View of mechanism for empty General Description. ALDOXHOI; hopper, 1,,j'earnied upon side standards 2, is provided, into whiehthe fibrous materials are'thi'own inaloosestate. a t, An endless apron, shown by dotted lines at 3 in fig.2, forms the bottom of the box,;and is moved in a the direction to carry t-lieIfibrous materials toward the frontwherethere a roller, 4, shown'by a dotted circlelin fig. '2. a i j a This roller 4- bas hooks fixed all over its surface,

, and, turning in the. direction shown by'the' arrow, 1 picks up the fibrous materials and carries them round over its top, any excessbeing prevented from passing a over by a vibrating paddle, 5. a a A revolving paidle,indicated by dotted'lines at 6 infigfll," and working undera hoodor cover,'7, beats l the fibrous materials oft the'hooked roller 4, so that they fallinto a weig'hing-scale,-8.l This scale Sis carried by arms 9 on ahorizontal spindle, 10,.supported brackets 11 l -{imd is counterbalanced by adjustable weights 13. Y a

To oneendof the weighing scale 8 there-is loosely wjointed'a pendent-rod, 14, having'at its bottom end a pin projecting across a-hook-toothed wheel, 15, shownseparately in fig, 3, anjd whichjs constantly revolving inside of an open box, 16. 'The rim oflthe box is nearly in 'eontactwith the teeth of the wheel,round a carding-machine.

A pulley, 36, on'thespindlc 30 of the booked roller the sides and bottom, but is'at thetop shaped to allow the pin of the pendent rod 14 to rise clear of the teeth, the top consisting of spri'ng, which allows the parts to yield when the point of atooth happens to strike the pin improperly. As soon 'as the accumulation of the fibrous materials in the scale Scanses the scale to begin'to descend, the pin of the pendent-rod 14 engages with the toothed wheel 15, and that wheel draws down the scale quickly, emptying it, and then carries it lip/again. The fibrous materials drop from the scale 8 down upon an endless apron, not shown in the drawing, but which carries them into the carding or other'machine. v

' ,The various movements hereinbefore described are all derived from-a transverse horizontal'shaft, 17, which is itself to be drivenfrom the carding or other machine by means of a-pitch, chain, or otherwise; A cord transmit-s motion from a pulley, 18, on the shaft 17, to apulley, 19, which'is on a stud, and which has fast to it'a pinion, gearing with a spur-wheel, 20,

' fast on the spindle of the, toothed wheel 15, whichi draws down the weighing-scale.

From anothcr pulley,.21, on "the shaft 17, accord transmits motion to two pulleys, one, 22, being on the spindle23- of the doifing-paddle 6, and the other, 24,

on a stud and having an. eccentric pin, whieh, by a connecting-rod, 25, jointed to a crank-arm onthe spindle 26 of the paddle 5, gives the vibrating motion to that paddle.

The hooked: roller 4 is driven by means of the spindle 23 of the doifingpaddle 6, a belt from that spindie-being passed round fast and. loose-pulleys 27 on an .inclined spindle, which has-fast on it a worm, 28, gearing with a worm-wheel, 29,,fast-on the spindle 30 of the hooked roller 4; From the positions of the parts, the belt tends to run on the upper pulley 27, whichis the fast one but when the weighlng'scale 8 is being emptied, a roller, 31, carried by a vertical rod, 32-, presses the belt down upon the loose pulley 27, in consequence of which the motion of the hooked 'roller ceases for the time.

T e '32 is held up by a catch-lever, 33, which engages under a shoulder formed on it, but when the weighing seale 8 begins to descend, a pin, 34, fixed to 'it, throws oil the catch-lever 33, and the rod 32 de-.

sceuds by it-s own weight, aided, ifnecessary, by a spring, '35. After each emptjiing of the scale 8 the feeding is discontinued until the rod 32 is again raised; which is done by a cam adapted to the speed and requirements of the carding or other machine. Thusit may be conveniently done'by. a cam on the spindle of the outermost roller of the feed or entering apron of transmits motion, by a cord, to a pulley, 37, on the spindle of one of the rollers of the endless apron 3 at the bottom of the box or hopper 1.

Claims.

We claim as our invention 1. In an apparatus for supplying material to carding and other machines, a self-discharging scale, substantially as described, operating as and for the purpose set forth.

2. In an apparatus for supplying material to card-' ing and other machines, a scale, operated substantially. as described, to automatically cut ofi' the supplywhen t begins its discharge.

waseo 3. The toothed wheels 15, in combination with the weighing and discharging device 8 and rod 14, substantially as and for the purpose described.

4. The supply eut-ofi', consisting of the catch-lever 33, pin 34, and rod 32, in connection with the scale, substantially as and for the purpose described. 1
